搬などに支障を来すこともない。 Therefore, in order to attach the swinging rod 1 to the case 2, first, as shown in FIG. While keeping the V-shaped protrusions 9, 10 provided on the upper surface of the support part in a state where they can pass through the guide groove 16 formed in the regulating part 15 of the swing center body 12, insert the protrusions 9, 10. The swinging center body 12 is inserted from the back side of the case 2 toward the front side so that it swings within the guide groove 16. Thereafter, by positioning the swing rod 1 within the range of the normal swing angle A as shown in FIG. 6B, the swing rod 1 is placed at both ends of the swing center body 12 as shown in FIG. A certain V-shaped groove 1
3 and 14 are respectively engaged with V-shaped protrusions 9 and 10 provided on the upper surface of the support body 8, and the regulating part 15 is loosely engaged with the gap d between the protrusions 9 and 10, so that the swinging rod 1 is swingably supported with its position in the front-rear direction restricted. In addition, in this state, the protruding part 8a of the support part 8 is located within the opening 11a of the frame 11, and when a force is applied to the swinging rod 1 to cause it to detach upward, the lower surface of the protruding part 8a is placed inside the frame 11. It functions as a detachment prevention means that comes into contact with the inner edge of the swing rod 1 and prevents the swing rod 1 from detaching upward. For this reason, the swinging rod 1 is supported by the support portion 8 in a non-removable and swingable manner within the range of the normal swing angle A. Also, when transporting this pendulum device,
Engage the locking claw 8 with the locking pin 4a and swing the swinging rod 1.
If the swinging rod 1 is kept in a non-swingable state, the swinging rod 1 is fixed to the watch mechanism case 2 in a non-removable manner, so that there is no problem in transporting the swinging rod 1.
